What happens in animal cells when mineral concentration is high and low in solution
slamgirl [31]

Answer:

Diffusion occurs when there is movement of minerals from an area of higher to lower concentration, till equilibrium is obtained.

Whereas Osmosis is the movement of solvents rather then the solute, from a solution of lower to a solution of higher concentration with the help of semipermeable membrane.

Explanation:

Diffusion is the movement of substances from area of higher concentration to an area of lower concentration of minerals, which mainly results in animal cells. Whether solute or solvent, diffusion occurs for both. Diffusion does not requires any semi permeable membrane. Diffusion occur in all state of matter, that solid, liquid and gas, whereas osmosis occurs only in liquid state. Osmosis requires semipermeable membrane and rate of which is related to concentration of solute dissolution in solvent medium. Only movement of solvent medium takes place. Classical example of osmosis is exhibited by cell membranes of animal cells. On the other hand diffusion is the spreading of perfume or fragrances to the external air.

The magnets point North when the Earth's magnetic field has (p2)<br><br>need some help :)​
Natali5045456 [20]
<h2><u>EARTH'S MAGNETIC FIELD</u></h2>

The magnets point North when the Earth's magnetic field has?

<h2><u>ANSWER</u></h2>

I think the best answer for this question is Magnetic Reversal or Geomagnetic Reversal.

In geomagnetism, the term "geomagnetic reversal" also known as 'flip', is the process by which the North pole becomes South pole and the South pole transforms into North pole.

<h2><u>THE MAGNETIC REVERSAL</u></h2>

The reversals happen on rare occasions when iron molecules start moving towards the opposite direction as other iron molecules around them within the Earth's spinning outer core.

Which of these is true for a daughter cell produced by mitosis?
cluponka [151]

The answer is A

Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.
